DUPLIGA'IOEF.

Specification of Letters Patent. Patented June Q5, Ili- Application filed July 7, isle. Serial in. 108,037.

To all whom it may concern:

Be it known that I, ALoIs BENJAMIN SA- LIonR, a citizen of the United States, and a resident of the borough of Manhattan, in the city and State of New York have inyented certainnew and useful Improvements in Duplicators, of which the following is a specification.

The invention relates to duplicators, and more particularly to that type of dupllcators in which a negative or reversed impresfor one of its principal objects to produce such a duplicator which may be simplyand cheaply constructed; and which shall be capable of easy, smooth, and rapid operation.

The invention consists in the novel construction, arrangement and combination of various devices, elements and parts, as shown in the accompanying drawings and fully described in this specification.

In the said drawings, Figure 1 is a side eleyation of my invention; Fig. 2 is a rear elevation of the same, showing the parts in another position; Fig. 3 is a section taken on the line 3-3 of Fig. 2 and looking in the direction of the arrows, showing the parts in still another position and Fig. at is a detail view to be hereinafter described.

In carrying my invention into effect in the embodiment thereof which I have selected for illustration in theaccompanying drawings and description in this specification, I provide a base 11, hearing uprights.

12, in which is journaled a shaft 13, rotatable by means of a crank 15 having a handle 14. "Rigidly mounted on the shaft 13, between the, uprights 12, I-provide a rotary frame comprising side members 16 and a curved bed 19. ()nc of the members 16 is provided with a series of holes 17, whose 'ularly Fig. 4).

23. I provide pawls 24 adapted to engage with said ratchets, said pawls being pivoted at 25 to levers 26, and also connected to said levers by means-of springs 29. The levers 26 are connected together at their in.- ner ends by means of a handle 27 pivotally secured to said levers, by means of which handle thelevers may be operated and the pawls 24 thrown into or out of engagement with the ratchets 23. A friction washer 30 is provided for the purpose of holding the levers 26 tightly together-and pressing the same against the handle 27, in order that the levers may remain in whatever position they may be placed by the operation of the said handle. I provide two guard plates tit tit

28, parallel to and adjacent the members 16,

which guard plates are adapted to prevent the 'dup icating film 22 from being displaced,

and one of which plates is provided with a slot through which the handle 27 may pass. Integral with the members 12 are eaten 510118 31, which extensions have journaled therein an impression roller 32, adapted to bear against the duplicating surface 22 when the rotary frame is moved, and which roller is provided with a gear wheel 33 rigidly attached to one end and adapted to engage with the rack 18. A second roller 34 bears against the roller 32, and its pressure thereupon may be adjusted by means of screws '37, which regulate springs 36, bearing upon blocks 35, which in turn press upon the end bearings 38 of the roller 34. (See partic- In a similar manner, the pressure of the roller 32 upon the duplicating film may be regulated by means of screws 39, springs 40, andblocksdl. Rigidly secured to the extensions 31 is-a shelf 42,- adapted to receive paper to be fed into the duplicator. A sheet of paper is shown upon this shelf and designated 4-3.

Un tlie rotary frame is a stop to adapted to limit the movement of the, said rotary frame in one direction by engagement with a portion of one of the members 12, a cushion stopA4 being provided if desired. The rotation. in the other direction. of the rotary frame is limited by an adjustable stop 46, mounted on the end of a spring lever t7, which lever His provided at its other end with a ring 48, whereby it is adapted to be rotatably mounted upon the shaft 13. The stop 4E6 may be moved oppohilt ltd. 1

site any of the holes 17,and will be held in engagement therewith by the spring lever 47. This stop 46 is adapted to strike against the position shown in Fig. 2, in which the rollers 21 are readily accessible from the rear. The end of the strip is secured to one of these rollers, and the rotary frame is then turned into the position shown in Fig. 1,

' in which position the duplicating film may hit be passed over the bed 19 without the impression roller 32 being in the way. The film is then passed over one of the rollers 20, around the bed 19, and over the other roller 20, the device returned to the position shown in Fig. 2, and the free end of the duplicating film secured to the other roller 21. The relative positions of the rotary frame and the duplicating film thereon are best shown in Fig. 3'. v A I The pawls 24 are then thrown'into engagement with the ratchets 23' and the duplicating film drawn taut .over the bed 19 by rotating the rollers 21 by iheans of cranks 44. When it is desired to move anew portion of the duplicating film over the bed, the pawls 24, are disengaged, the handles 44 manipulated until the desired portion is moved into place, the pawls again placed in engagement, and the film tightened.

A sheet of paper upon which is written in suitableink the matter to be. copied is placed upon the shelf 42, and its lower end pushed downward as far as possible upon the rollers 32 and 34, and, the parts being in the position shown in Fig. 1, the handle 14 is operated to bring'them into the position shown in Fig. 3. The motion of the rotary frame is communicated to the impres-v sion roller 32 by means of the rack and gear wheel, and from the impression roller to the roller 34 by friction. 1 The end of the paper is grasped'by the rollers 32 and 34, and passed between them-upon the duplicating film. The motion of the duplicating film causes the end of the paper to pass between it and the roller 32, and as the rotary frame continues to turn, more and more of the paper is brought into contact with the duplic'ating surface.

The motion of the rotary frame is stopped at such a point thatwhen the paper upon which copies are to be made is 'inserted in the machine, a small portion of the last inserted end shall remain upon the shelf 42,

and not he passed between the rollers 32 and 34. The movable stop 46 is then set at such a point that the motion of the rotary frame will be automatically stopped at this place.

.fl*1e movement of the handle 14 is then reversed, and the parts returned to the position shown in Fig. 1, reversing the movement of the impression roller 32, and causing it to eject the paper upon the shelf 42.

that the paper, after passing between the rollers 32 and 34, would travel upward in stead of downward, in which case the roller 34 would become the impression roller, and would be so set as .to bear against the duplicating film. Another possible modification is the insertion of a paper guide adapted to deflect the paper upward or downward as desired, immediately after it passes between the rollers 32 and 34. It will also be readily understood that the inventionmight be so constructed that the frame bearing the duplicating surface would remain stationary,

and the part of the device carrying the im-- pression roller be reciprocated thereover.
